KT-LCD3 for TSDZ2 Flexible OpenSource (FOS) Firmware Upgrade
KT-LCD3 pre-wired with 5-pin green female higo connector to work with same harness as 850C color display on TSDZ2 with FOS firmware. The optional Bafang 1 To 4 Cables below allow use of all of the bafang throttles and brake cutoff sensors. These are all selectable for inclusion with the KT-LCD3 display.The harnesses available below are also compatible with the stock 850C color display and will be plug and play when the 850C open source firmware is ready.
The KT-LCD3 and the custom female 1to4 cable are custom made at the factory as specified by Electrify Bike Co. to work with the FOS firmware. There are no splices on any of the cables.
This KT-LCD3 display has the stock KT firmware in it but is ready to flash with the FOS Firmware. You can do this following the instructions on github or you can have us do it for a small fee. Select which you want below.
If you purchased a KT-LCD3 display somewhere else it is not compatible with the bafang style 1to4 cables available on this page. It is also not compatible with the 850C if ever want to upgrade. You can splice a female 5 pin green connector onto it (drop us a note for pinout). Oryou can follow the directions to interface it to an alternate non-Bafang type 1to4 cable provided by Tomtom50 on Endless Sphere.

Thanks to the FOS firmware developers:
The developers of the TSDZ2 FOS firmware are talented engineers. They developed this TSDZ2 augmenting firmware with a huge investment of their time as a public service to promote ebike use and environmentally friendly transportation. To say thanks and to help defray the cost of fried controllers, displays and other things they bought out of their own pocket, Electrify Bike Co. will make a donation to them equal to 10% of the sale of this product.
See information about which 1 to 4 display harness to use below.
Splicing a cable for 6 pin TSDZ2
If you have an 8 pin female display connector on your TSDZ2 then you probably already have the harness that works with this display. You probably bought a motor with an 850C or 750C display. If you still need this harness click here for the regular 1T4 harness.
If you have a 6 pin female display connector on your TSDZ2 controller click on the tab above for what to buy and splicing instructions.

Both the KT-LCD3 and the 850C displays will work with this 6 pin spliced cable. 2 wire brake cutoffs will also work including the mechanical levers and magnetic sensors soldon this page. However, the throttles and HWBS brake cutoff will not work as they require additional wires. The HWBS requires +5 and the throttle requires +5 and throttle signal. These are available on the controller circuit board. If you would like to add them there is information on Github that explains how to do it. The throttle connections are shown on the temperature sensor page and the HWBS brake is shown here.
